Investigation of Phosphorus Cycle Dynamics Associated With Organic Carbon Burial in Modern (North Pacific) and Ancient (Devonian and Cretaceous) Marine Systems; Strengths and Limitations of Sequentially Extracted (SEDEX) Phosphorus Data

Description:

Periods of time characterized by widespread accumulation of organic carbon (Corg) -rich deposits have been interpreted to form as a result of increased rates of marine primary production and oxygen-deficient conditions in bottom and pore waters. Yet, debates persist regarding the source of nutrients (in particular phosphorus (P)) to marine...

Studies on the S-velocity Structure of the North American Upper Mantle

Description:

Several surface wave tomographic studies of the upper mantle structure beneath North America are presented, which take advantage of high quality seismic data, primarily recorded in the last decade, to create better resolved S-wave tomographic models. The first study presents a regional 3D model, IL05, of the upper mantle beneath...
